LOS and Impassable Terrain Corners

[LOS and Impassable Terrain Corners]

I put the question to Fantasy Flight and got a very prompt reply.  Regarding the necessity of being adjacent to impassable terrain for opposite corners to obscure LOS, they say:

"When a diagonal line of sight between two units would cross two opposite corners of impassable terrain, line of sight is blocked between those units. If any of those units are not adjacent to the impassable terrain that would block line of sight in this way, line of sight is still blocked between those units.

 

I hope this has answered your question. Happy Gaming!"

 

It seems that most folks have been playing this way already.  It is nice to know that that is how they intended it to be played.  Happy Gaming indeed!!

[Combined corner cover]

Sorry to jump in late on this but am new to Dust and confused by the LOS and opposite corner rule.  TallDwarf asked what would happen if the Heavy Laser Grendadiers were one square North and East.  Would LOS be still blocked by the opposite corners?  I have been playing it would not be.  The rules state "If a unit is adjacent to impassable terrain, it cannot target a unit who is ALSO adjacent to impassable terrain when the units receive corner cover from different sides."  Since the Grenadiers would, by moving, not be adjacent to the corner, LOS is restored despite the line going by 2 opposite corners.  Or not?  Thanks for any insight.  I love this game!
